[P1] Improve app/github-actions Workflows - 70% PR Rejection Rate

[github-actions]

Performance Issue

Agent Family: app/github-actions workflows
Current Performance: 30% PR merge rate (70% rejection)
Target: 60%+ merge rate
Impact: Significant resource waste from rejected PRs

Problem

Workflows running under the app/github-actions identity are creating 33 PRs with only 30% merge rate in the last 30 days. This 70% rejection rate indicates:

1. Poor scoping - PRs may be too large or unfocused
2. Inadequate validation - Changes not tested before PR creation
3. Misaligned acceptance criteria - PRs don't meet project standards

Evidence

• Last 30 days: 33 PRs created, only 10 merged (30% rate)
• Pattern classification: Over-creation with low quality
• Impact: ~23 rejected PRs represent significant wasted compute

Analysis

Sample of recent app/github-actions PRs shows:

• Daily automation updates (actions versions, dependencies)
• Documentation updates
• Chaos testing PRs (expected to close)
• Instructions sync PRs

Many rejections appear to be from:

• CI failures (lint, test, build)
• Chaos test PRs (intentionally closed)
• Outdated or conflicting changes

Recommended Actions

Short-term (< 1 week)

1. Implement pre-flight validation:

   • Run make agent-finish before creating PRs
   • Add lint and test gates to workflow
   • Validate no conflicts with main branch

2. Exclude chaos test PRs from metrics:

   • Chaos test PRs are expected to close
   • Track separately from production workflows

3. Analyze rejected PRs:

   • Review last 10 rejected PRs for common patterns
   • Identify most common rejection reasons
   • Add specific validation for those cases

Medium-term (< 1 month)

4. Add quality gates:

   • Require passing CI before PR creation
   • Add automated formatting checks
   • Validate commit message quality

5. Reduce output volume:

   • Batch related changes together
   • Reduce frequency of daily automation PRs
   • Focus on high-value changes

6. Implement feedback loop:

   • Track rejection reasons in structured format
   • Adjust workflow prompts based on common issues
   • Monitor improvement over time

Success Criteria

• PR merge rate > 60% for app/github-actions workflows
• All PRs pass CI checks before creation
• Rejection reasons documented and addressed
• Chaos test PRs excluded from quality metrics

Metrics to Track

• Weekly PR merge rate
• Common rejection reasons
• Time-to-merge for accepted PRs
• CI failure rate
